IMPROVEMENT IN CAR-STARTERS.

The Schedule referred to lnthese Letters Patent and making part of the same.

Beitwknown that 'I, Bonnier-Boonrmus, of the city of New York, in the county of New; Xork and ,State of New York, have invented a new and useful Improvement in Gar-Starters; and I dohereby declare that the following is a full, clear, and exact description of the same,-.reference being had. to the ac companyiug drawings and to the letters of reference rnarkedthereon;

1 'My invention consists of certain mechanism used in operating the starters of railroad-cars, which will be fully described hereafter.

In order to enable others to make and use my invelition, I will proceed to describe its construction and operation with, reference to .the accompanying ,Figure 1 is an inverted plan view.- 1 1 Figure 2 isa sectional elevation showing the method Figure 4 is a sectional view, showing the action of the spring a upon thediskD, h 1 A A are the side beams, and B B the end beams, 3 forming together the frame-work of a railroad car, this frame carrying the usual wheels 0 O, on thejaxle 1 1 ,F, the ends of which turnin appropriate boxes in the brackets G. r

E is a pulley, which is allowed'to turn freely on the axis F, until it is clutched by the disk D, when the motion imparted to it by the traction-chain O isjtranss mitted to the axle F,which is thereby cansed'to reyolve.

Upon the axle F is arranged a sleeve, 7;, upon which is secured a disk, D, on the faceaof which are-formed two or more annular V-shaped ridges, g, whiel1.coincide with a similarly-shaped depression formed in the double pulley E.

aaare rods or wires, onwhich the. diskD slides 1 when operated'by thespriri'g at.

Upon the pulley E are arranged two grooves, cross- 1 ing each other at certain points, for the chain to play in, said chain being fastened at one end'to a spring, ,I, 'or, if preferable, a weight, or the use of an endlesschain, 01' by any equivalent means which will accomplish the same result of drawingthe chain back when desired.

The other end of the chain has a hook, P, which is attached to a roller, in, playing in the ways i 1 His a slotted projection arranged perpendicularly or oblique, as maybe desirable, in which the chain 0 works Thisis an important part of my invention, and one which is believed to be entirely new, always keeping the horse in close proximity to the car.

K is a cranked shaft which works in the bearings I It.

By the use of the key It, shown in fig. 3, one of the cranks is forced against the spring'n, which drives the disk D, having the V-shaped ridges 9 against the serrated face of the pulley E, thereby coupling the starter or loose pulley E to the axle of the car.

1 L is a lever, worked by the hand or foot, which operatesfnpon the chain to freeit when desired, said 1 lever being kept in place bythe springs J J.

The operation of my starter is as follows:

The car being at rest, and the hook 1? being at the lower part of the guides,'if it is desired to start the car the cranked shaft K is depressed, which acts against the spring a and throws the clutch or disk 1),

into gear with the pulley E.

The draft of the team then acts through the pulley E to revolve the wheels and start the ear, and, as the axle revolves, the chain 0 and roller m follow up the ways in the slotted projections H, until, catching upon the cam L, and then being detached from the cam L, each part of the starterreturus to its former bination with the chain 0, hook P, and roller m, as

and for the purpose set forth.
